Use a cold chisel to cut a notch in the edge of the bolt. Then turn the chisel
so it is somewhat tangental to the edge of the bolt and hit it a few times. I
have NEVER had ANY success using penetrating oil on these or ANY OTHER frozen
bolt. An acetylene torch will probably also work, but propane is not hot enough
because there is just too much steel there. You don't want to warm things up
around there too much in general because there are things inside that you can
Once the bolts are out you will find that the drum is stuck; use a propane torch
to heat the drum just outside the parting line from the hub. This will let loose
with a sudden "Tink" and you can pull the drum off by hand. Carefull, it's hot!
